Abstract

Electrode temperature controlled AC corona discharge inception voltages (CIV) of a nonuniform field electrode system and the characteristics change of CIV in the presence of a barrier is investigated. Reduction in the breakdown voltages of the gap for negative standard impulse applications was observed as the point electrode temperature reached 200°C and the characteristic occurrence was repeated in the presence of a pressboard barrier
